摘要
介绍了一种新型单片机功率因数自动寻优控制的节电系统。它以异步电动机的功率因数作为控制参量,使电动机始终稳定地运行在对应一定负载的最佳值上,从而实现异步电动机的功率因数和效率最优。现场运行证明,当电机的实际运行负载低于45%额定负载时,节电效果显著。
New powersaving system of single chip computer control of automatic seeking best value of powerfactor is introduced. It uses powerfactor of asynchronous motor as control parameter and can make motor run steadily at best value corresponding to definite load, so as to achieve the best of powerfactor and efficiency of alternating motor. Operation on site testifies that the effect of powersaving is prominent, as actual operating load is under 45 % of ratedload.
